Research

Last updated: January 2026

My current research interests are on the following domains:

  1. The development of research methodologies of a computational nature to social science problems, in particular, in behavioural science research.

  2. The use of causal machine learning combined with experiments in behavioural and social sciences.

  3. Applications of evolutionary thinking in the social sciences.
